[ http://jira.qos.ch/browse/LBCLASSIC-216?page=com.atlassian.jira.plugin.syste... ] Joern Huxhorn commented on LBCLASSIC-216: ----------------------------------------- I agree that this issue should be fixed in ThrowableProxyUtil. Beside that, I'd like to point out that the documentation of Throwable http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Throwable.html#getStackTra... states, that getStackTrace() is required to return an empty array if no stacktrace is available. If this happens to you then there is a bug somewhere.
